Coverage
Domain-specific taxonomies for every major sport. Our annotators understand the rules, not just the pixels.
22-point skeletal tracking & complex event recognition — passes, tackles, offside.
Shot charts, pick-and-roll detection, and player spacing analytics.
Ball tracking, pitch map analysis, and batsman stroke mechanics.
Player skeletal tracking, stick flex analysis, and high-speed puck trajectory.
Ball trajectory prediction and stroke mechanics analysis.
Swing biomechanics and high-precision ball flight telemetry.
How We Work
Every engagement starts with understanding your requirements in detail. We don't do one-size-fits-all.
We understand your use case, data schema requirements, volume, format preferences, and delivery timeline. No templates — every engagement starts from your specific requirements.
We propose a tailored annotation workflow, team structure, and QA framework designed for your specific sport and data type. You review and approve before anything starts.
We deliver a sample dataset so you can validate quality, schema alignment, and accuracy before committing to full production. Zero risk, full visibility.
Our expert team begins full-scale annotation with continuous QA checks, accuracy monitoring, and a dedicated project manager keeping you updated every step.
We grow with your needs. Add new sports, increase volume, refine schemas, or expand scope — your dedicated team scales with you, not against you.
What we do
Seven disciplines we are known for, three more in scope. Your schema, your format, your pipeline.
71
Event groups mapped
Hierarchical event groups tagged frame-accurately against your own schema.
407
Sub-events defined
Sub-events and qualifiers resolved down to five layers of depth.
98%
Re-ID accuracy
Persistent identity across cameras, through occlusion and substitutions.
25–30Hz
Tracking rate
Speed, distance, sprint counts and team shape from raw trajectories.
3-layer
QC pipeline
Independent audit passes with inter-annotator agreement scoring.
56
Hockey sub-events
Zone entries, loose puck recoveries and shot danger for ice hockey.
120fps
Ball-track capture
Serve patterns, rally length and shot-by-shot point construction.
Video & Frame Annotation
1M+ frames labeled
Skeletal & Pose Keypoints
22-point skeleton
Semantic Segmentation
20+ sports covered
Who We Serve
Your model quality starts with data quality — regardless of which segment you build for.
Your models process thousands of hours of footage weekly. Generic vendors break on player overlap, occlusion, and rapid movement — sports-trained annotators don't.
Bounding boxes won't train a biomechanics model. Your systems need 22-point skeletal precision — annotation depth most vendors cannot deliver.
One frame of annotation error breaks your AR overlay. We deliver frame-perfect event synchronization at the precision live broadcast demands.
Annotation errors corrupt your prediction models and distort your odds engine. Our event pipelines are built for the data fidelity your risk infrastructure requires.
About Us
Train Matricx is a specialist data service agency. We combine deep sporting knowledge with rigorous annotation methodology to produce high-quality, structured sports data that powers AI models, betting systems, media products, and analytics platforms worldwide.
Behind every dataset we deliver is a team of human experts who understand the game — not just the data. Our annotators are former athletes, coaches, statisticians, and passionate sports professionals with years of first-hand experience in their disciplines.
What sets our team apart
Our global team covers live events around the clock, across all time zones — so your data is ready when the final whistle blows.
Every data point is reviewed by annotators who know the sport. We catch what algorithms miss — contested calls, context, nuance.
We deliver in the format your system expects — JSON, CSV, XML, direct database feeds, FTP, or API. No transformation work on your side.
Sports happen everywhere. Our annotators cover events in multiple languages and regional contexts — European leagues, Asian markets, and beyond.
